Circular dichroism of benzylidene derivatives of glycerol and mannitol

Abstract

The c.d. spectra are reported for a series of benzylidene derivatives of glycerol and mannitol containing 1,3-dioxolan, 1,3-dioxan and 1,3- dioxepan ring systems. The signs of the Cotton effects of ¹L_b and ¹L_a transitions of the phenyl chromophore have been rationalized in terms of recently proposed sector rules for these transitions.
